The Grand Canyon State Welcomes You!

摘要

The Grand Canyon State welcomes the Geological Society of America Annual Meeting & Exposition to our capital city of Phoenix for the first time in more than three decades. It's an especially auspicious year for GSA to come here, as 2019 marks both the 150th anniversary of John Wesley Powell's first expedition through Grand Canyon and the 100th anniversary of Grand Canyon National Park! Arizona is indeed a land of textbook geology, where you can set your feet, hands, senses, and camera on the exposed rock record of nearly two billion years of deep time.
